Abstract

The present invention relates to a method of blocking electromagnetic interference and shielding apparatus, which is used to setting a shielding area on the electronic components on the two sides of a printed circuit board and in a electromagnetic wave scattering scope of a circuit layout; through a first shielding apparatus, whose bottom is soldered on the obverse surface of the printed circuit board, installed on the surface of the circuit board with height limitation, the shielding area can be covered; at the opposite side corresponding to the shielding area, a second shielding apparatus is installed capable of completely covering the shielding area which defines a height-limiting area in the zone with height restriction; the second shielding apparatus has a hollow cap and at least one extension part in which the cap has side walls installed around and the extension part is disposed by the extension part of the circumference of the cap; the extension part can be completely covered on the surface of the printed circuit board with height restriction; by soldering the bottom of the second shielding apparatus on the surface of the opposite side of the printed circuit board, the effect of shielding electromagnetic wave can be obtained.
